[chbot] ESP8266 vs ESP32

[Stephen Irons]

My colleague did not end up using BLE on the WiPy2. At present, Micropython
does not provide access to all of the features, and proved to be buggy for
the features he wanted to use. That was a few months ago, so things might
have changed by now...the problems of using a new(ish) device with ESP32
libraries and Micropython libraries all in a state of flux...we hope things
will get better.
